Error installing ruby 1.9.3

Question

I'm trying to install Ruby 1.9.3 using rvm. However, when I type:

rvm install 1.9.3

I get the following error:

ERROR: Error running 'make ', please read /Users/nick/.rvm/log/ruby-1.9.3-rc1/make.log
ERROR: There has been an error while running make. Halting the installation.

I'm running Mac OS X Lion and my current version of Ruby is 1.9.2.

Edit: make.log:

Answer 1

The simpler, more general solution is to explicitly install the offending package and then reinstall with that package. In my case, it was aborting on openssl_missing, so:

rvm pkg install openssl
rvm install 1.9.3 -C "--with-openssl-dir=$HOME/.rvm/usr"

For your case, it's probably:

rvm pkg install readline
rvm install 1.9.3 -C "--with-readline-dir=$HOME/.rvm/usr"

This of course assumes that you installed rvm as yourself. Change accordingly...

This is an issue with readline. Try compiling readline yourself from source:

curl -O ftp://ftp.gnu.org/gnu/readline/readline-6.1.tar.gz
tar xzvf readline-6.1.tar.gz
cd readline-6.1
./configure --prefix=/usr/local
make
sudo make install
